摘要： An heat exchanger including a shell for flow of a first fluid and a plurality of tubes for flow of a second fluid in heat exchange relation therewith. A tubular member is concentric with at least a portion of a tube to define a space between the tube and tubular member. The tubular member includes at least one radially outwardly longitudinally extending projection portion for effecting flexing of the tubular member radially outwardly so that a minimum clearance between the tube and tubular member may be provided, and so that the tube may be inserted in and removed from the tubular member to provide greater accessibility for welding tubular members to tube sheets during assembly. Oxygen may be introduced into the space between the tubular member and tube to combine with tritium which may diffuse through the tubular member wall to prevent diffusion of the tritium through the tube wall.

摘要： A heat exchanger with at least one main tube, closed off at one end, into which compressed air, which is to be heated, is admitted and, after being heated, is removed. The main tube has at least two channel guideways which are separated from one another in the longitudinal direction. U-shaped or curved compressed air lines project from the main tube and contact the hot gases. Each compressed air line is connected at one end to the channel guideway of the main tube into which compressed air is admitted, and at its other end with the channel guideway through which the heated compressed air is removed. The compressed air lines are formed primarily from hollow bodies, which extend in the direction of flow of the hot gas and which preferably are tapered at the inflow and outflow ends in order to aid the flow.

摘要： In a heat exchanger for heat transfer between ammonia converter effluent recycle gases and water, a plurality of U-shaped tubes have their inlet and outlet ends connected to a tubesheet which divides the interior of a shell into a pressure chamber and a heat exchange chamber containing the tubes. The pressure chamber is divided into an inlet chamber and an outlet chamber with the cooled recycle gases flowing into the outlet chamber and cooling the inlet chamber. The tubes are formed of ferritic steel and are welded to the tubesheet. A tubular cladding of nitriding-resistant material extends through the tubesheet at the inlets to the tubes and spaces the recycle gases from the tubes at the inlet ends.

摘要： A body of water having a liquid level and an outer edge is provided with a water heater having a collector formed as an array of adjacent and substantially concentric annular flexible tubes that surround the body at the edge and that has a rectified equal to at least 30 times its horizontal cross-sectional width. The tubes have exposed upper surfaces and feed ends connected to a feed manifold and return ends connected to a return manifold. Respective feed and return conduits are connected to the feed and return manifolds and both open into the body of water below the liquid level thereof. A pump is provided in one of the conduits for drawing water from the body into the feed conduit, then passing it sequentially through the feed conduit, the feed manifold, the tubes, the return manifold, and the return conduit, and for expelling the water into the body from the return conduit. The array has a surface area equal to approximately 50% of the surface area of the body of water being heated, and the pump is relatively small so that at most a 2.degree. C. temperature gradient is obtained between the feed and return manifolds.

摘要： A low profile, light weight and economical evacuated-bottle solar collector module is described. A row of off-shelf high vacuumware bottles as used for soup or coffee, without their usual reflective silvering, are fitted with absorbers and have their open ends fixed in grooves for support and thermal insulation in a combination insulation-support carrying frame. Holes are adapted in the frame for passage of the heat transfer fluid. Additional insulation members form header ducts for an air transfer medium or provide insulation and support of liquid tight tubing for a liquid transfer medium.

摘要： A heat exchanger for cooling process gases which are under high pressure and temperature. The withdrawn heat is used for high pressure steam generation in accordance with the natural circulation principle. The heat exchanger comprises U tubes suspendedly inserted in a plate or tube sheet. Two chambers are provided above the plate, are separated from one another, and are intended for the coolant-steam circulation. A housing surrounds the U tube bundle and is connected to and below the chambers. The housing has at least one process gas inlet and at least one process gas outlet. One arm of each U tube is constructed as a double tube. The inner tube has the function of a gravity tube, and the remaining annular conduit, as well as the remainder of each U tube, have the function of risers.
